  • Developer

A base connection represents the authenticated connection between a source and Adobe Experience Platform.

This tutorial walks you through the steps to create a base connection for Azure Data Explorer using the Flow Service API.

Getting started

This guide requires a working understanding of the following components of Adobe Experience Platform:

  • Sources: Experience Platform allows data to be ingested from various sources while providing you with the ability to structure, label, and enhance incoming data using Experience Platform services.
  • Sandboxes: Experience Platform provides virtual sandboxes which partition a single Experience Platform instance into separate virtual environments to help develop and evolve digital experience applications.

The following sections provide additional information that you will need to know in order to successfully connect to Azure Data Explorer using the Flow Service API.

Gather required credentials

In order for Flow Service to connect with Azure Data Explorer, you must provide values for the following connection properties:

CredentialDescription
endpointThe endpoint of the Azure Data Explorer server.
databaseThe name of the Azure Data Explorer database.
tenantThe unique tenant ID used to connect to the Azure Data Explorer database.
servicePrincipalIdThe unique service principal ID used to connect to the Azure Data Explorer database.
servicePrincipalKeyThe unique service principal key used to connect to the Azure Data Explorer database.
connectionSpec.idThe connection specification returns a source’s connector properties, including authentication specifications related to creating the base and source connections. The connection specification ID for Azure Data Explorer is 0479cc14-7651-4354-b233-7480606c2ac3.

For more information about getting started refer to this Azure Data Explorer document.

Using Experience Platform APIs

For information on how to successfully make calls to Experience Platform APIs, see the guide on getting started with Experience Platform APIs.

Create a base connection

A base connection retains information between your source and Experience Platform, including your source’s authentication credentials, the current state of the connection, and your unique base connection ID. The base connection ID allows you to explore and navigate files from within your source and identify the specific items that you want to ingest, including information regarding their data types and formats.

To create a base connection ID, make a POST request to the /connections endpoint while providing your Azure Data Explorer authentication credentials as part of the request parameters.

API format

POST /connections

Request

The following request creates a base connection for Azure Data Explorer:

curl -X POST \
    'https://platform.adobe.io/data/foundation/flowservice/connections' \
    -H 'Authorization: Bearer {ACCESS_TOKEN}' \
    -H 'x-api-key: {API_KEY}' \
